When wide open and just shooting around, I shoot roughly 75-80% from behind the arc. In games, I shoot around 55-60% from behind the arc. So it drops around 20%.
My FT% in game is around 90%, and it's around 95-97% when just practicing. So that drops around 5-7%
I'm not really sure about the midrange, I've never really been able to keep count on 2-pointers because so much of my 2-point baskets are layups, floaters, runners, and the like. When shooting around, I almost never miss mid-range jumpers but I've never really kept count.
